Oncor Electric Delivery

Oncor is the transmission and distribution utility (TDU) for roughly 3.7 million premises across north, central, west, and east Texas. Because Texas operates a deregulated retail electricity market, Oncor delivers power but does not sell it; customers buy energy from retail electric providers (REPs), and any EV-specific time-of-use plan is set by the REP rather than by Oncor. On the EV side, Oncor's direct customer offerings are limited to a Level 2 charger discount routed through the Take a Load Off Texas Retail Products subprogram, plus a closed Toyota vehicle-to-grid research collaboration that is not open to general customer enrollment.

Take a Load Off Texas, Retail Products: Level 2 EV charger discount

TODO: re-verify exact discount amount (researcher could not confirm against oncor.com retail products page; aggregator sources reported amounts ranging from up to $100 to up to $500, which is too wide a range to publish)

Open to Oncor residential customers, including renters with landlord approval for hardwired installs; incentive is applied at point of sale by a participating retailer, not as a post-install rebate.

Oncor does not set residential time-of-use rates because Texas operates a deregulated retail electricity market: Oncor owns and operates the wires, meters, and substations, while customers buy energy from retail electric providers (REPs). Any EV-specific TOU plan, including the "free nights" structures popular in Texas, is set by the REP rather than by Oncor. Drivers comparing REP offers should focus on the kWh price during the overnight window they actually charge in, not the headline rate.

Oncor's direct customer-facing EV program is the Take a Load Off Texas Retail Products subprogram, which discounts a qualifying Level 2 charger at point of sale through a participating retailer rather than as a post-install rebate. The exact discount amount published by Oncor is not currently consistent across third-party aggregators, so customers should confirm the live discount on the retailer's site at purchase time. Oncor does not run a residential or commercial managed-charging program; the closed Toyota vehicle-to-grid research collaboration is not open to general enrollment.

Oncor's footprint covers about 3.7 million premises across north, central, west, and east Texas, including most of the Dallas-Fort Worth metroplex. As a transmission and distribution utility, Oncor's role on the EV side is limited; the determinative variables for drivers in this territory are which REP they choose and what overnight rate that REP charges. PUCT rules also bar ERCOT TDUs from owning or operating public chargers, so the public charging build-out in Oncor territory is driven by retail providers, networks, and city programs rather than the utility itself.
